Renewed ,August 3, 1935 10 Claims.

This invention relates to windshields for motor vehicles and more particularly has reference to windshields of the character which are swingably or pivotally supported at their upper edges.

It is an object of the invention to provide locking mechanism for rigidly and securely holding a Windshield in any desired position, the entire locking mechanism and its control being disposed outside the line of vision through the windshield.

A further object of the invention resides in the vprovision of a locking device for windshields which, with the exception of the control mechanism, is entirely concealed behind the side frame members of the windshield without encroaching upon the area of vision through the windshield.

It is a still further object of the invention to provide locking mechanism of the character set forth which is adaptable for mounting upon the frame of any type of pivoted windshield without affecting the design or increasing the cost of the frame.

Still another object of the invention is to provide locking mechanism which will rigidly holdthe Windshield in any adjusted position without vibration due to wind pressure or motion of the vehicle.

A further object of the invention resides in the provision of a windshield locking device which is freely and separately adjustable at both ends to give greater or less lockingl action and to compensate for wear of parts of the device.

Still another object of the invention is to provide locking mechanism of the nature referred to which is simple in construction, efcient in operation, and economical in manufacture.

Other objects and advantages of the improved windshield locking device will appear from the more detailed description thereof.

For a fuller understanding of this invention reference will be had tol the accompanying drawings illustrating one preferred embodiment but it is'to be understood that the invention is not to be construed as limited to the specific showing of the drawings.

In the drawings, Fig. 1 is a fragmentary front view of a known windshield construction having this improved locking mechanism applied thereto, the mechanism being shown in the locked position;

Fig. 2 is an end view of the construction shown in Fig. l and illustrating in dotted line an adjusted position of the device;

Fig. 3 is a cross-sectional view taken on a line through the upper portion of the supporting arm ing swingable on its pivot 22 as indicated in and showing its pivotal connection to the body pillar of a vehicle; and

Fig. 4 is a cross-sectional view through the control mechanism and is taken on the line 4-4 of Fig. 1. 5

Throughout the several views of the drawings like reference characters indicate like elements of construction.

Referring more particularly to the drawings, at A is indicated generally a windshield having 10 upper frame member I, lower frame member 2, and window 3 therebetween. In the lower frame member 2 is supported a pair of rods 4, the opposed ends of which are bent over as shown at 5. Between and in contacting relation with the l5 ends 5 is positioned a cam 6 which is securely and rigidly fastened to a rotatable handle and central operating control 'I having a stop member 8.

Fixed to the windshieldA side frame member or channel 9, by means of screws I0, is a casing II having a slot I2 extending longitudinally thereof. A shaft I3 is disposed within the casing II, said shaft being adapted for slight r0- tational movement on its axis within the cas- 25 ing. The lower end of shaft I3 protrudes from the casing and is bent inwardly toward side channel 9 as shown at I4, the extension ld of shaft I3 being bifurcated to receive collared bushing I5 screw threaded, as shown, onto the outer end of one of the rods i and freely adjustable thereon. The portion of shaft I3 within the casing is cut longitudinally (see Fig. 3) to pro-vide a slot I6 therethrough equal in width to slot I2. Positioned for sliding movement within slot I2 35 of the casing and slot I5 of the shaft is a supporting arm or brace I'I provided with projections I8 at its inner lower end to prevent the lower end of arm I'I from being withdrawn through the slots. It will thus be seen that arm I'I passes through and is in contact with the edges of both slots I2 and I and is free to move lengthwise thereof while the lower end of the arm is at all times retained in the slots by virtue of projections I8.

The upper end of arm II is pivoted on and securely held by screw I9 mounted on bracket 20 which in turn is rigidly fastened to body pillar 2l of the vehicle, the entire windshield A beposition about its pivot 22.

upon the mechanism is placed in free or unlocked position and arm I'I is free to swing inwardly and outwardly about bearing screw i9 and to slide in slots i2 and I6 of casing II and shaft I3 respectively. In this unlocked conditionV the windshield may be swung into any desired The Windshield having been properly adjusted, cam 6 is now rotated through handle 'I back into the position shown in Fig. l, this action causing rods 1I to move outward toward the sides of the Windshield and to exert and maintain a force or pressure on the lower` end I4 of shaft I3 tending to rotate the latter about its axis in casing I I. Such axial movement of the shaft in the casing causes arm II to be pressed or bound between one edge of slot I6 in the shaft and the opposite edge of slot I2 in the casing, the resultant pressure furnishing sufficient friction to prevent arm I1 from being moved lengthwise in the slots. Movement of the windshield is thus prevented and the same is accordingly firmly locked in the desired adjusted position.

By reason of the bushings I5 on the opposite ends of rods 4, the mechanism is freely and separately adjustable at both ends to give greater or less locking action and to compensate for wear of the Yparts of the device. The stop member 8 on handle 1 is provided to limit the movement of the latter to the necessary operating arc.

From the foregoing it will be seen that we have devised mechanism for rigidly locking a windshield in adjusted position, the entire device, except for control handle 1, being concealed by the frame or channel members of the windshield and all parts disposed out of the line of vision through the latter, the mechanism being simple in construction and operation.

Although we have illustrated and described the invention with considerable particularity, it is to be understood that Various'changes and modifcations may be made therein without departing from the Vspirit and scope of the invention las defined in the appended claims. Y
